Interfacial Tension Test using a Du Nouy Ring

WebThe Du Nouy ring method is used to measure static surface and interfacial tensions of liquids (Hiemenz 1986, Couper 1993). The apparatus required to carry out this type of measurement consists of a vessel containing the liquid (s) to be analyzed and a ring which is attached to a sensitive force-measuring device (Figure 5.13). WebJan 1, 2009 · Equation (2.7) shows the relationship for the calculation of surface tension by the du Nouy ring method. In this equation, P T is the total force on the ring which is measured, P R is the weight of the ring, R is the radius of the ring, and γ ideal is the ideal surface tension. In practice, a meniscus correction factor is required because the ...
